论文摘要
Aharonov-bohm效应使人们可以通过在零磁场区域中传递电流来证明磁载体电位的物理意义。 在标准（A {\ em两缝样}）设置中，导电环被磁通刺穿，并且电子对电子的量子干扰同时观察到两个环臂。在这里，我们通过分析通过逃生波的传输表明，经受螺线管磁电势的石墨烯中的弹道Corbino磁盘可能显示出Aharonov-Bohm的电导振荡，尽管电流仅通过单个导电元件流过单个导电元件。
The Aharonov-Bohm effect allows one to demonstrate the physical meaningfulness of magnetic vector potential by passing the current in zero magnetic field regions. In the standard (a {\em two-slit-like}) setup a conducting ring is pierced by magnetic flux and the quantum interference for an electron passing simultaneously the two ring arms is observed. Here we show, by analyzing the transport via evanescent waves, that the ballistic Corbino disk in graphene subjected to a solenoid magnetic potential may exhibit the conductance oscillations of the Aharonov-Bohm kind although the current flows through a single conducting element only.
